Only minus was not the fault of the hotel but the parking situation in Lauterbrunnen. The main car park here can be full at busy times adding about 1hr to your journey as you drive back or further down the valley to find a park and ride parking space, this can involves a chilly wait for a bus back into Lauterbrunnen. Parking can be booked in advance but only for a minimum of 5 days which doesn't really help for weekend's or overnighters.
A tip would be to park in Interlaken or Wilderswil and get the very enjoyable train ride upto Wengen from there, this only adds about 20 mins to your trip and saves the hassle or driving around looking for parking.
We stayed for 2 night's over new years at hotel caprice.
Views from the valley facing rooms are amazing/breathtaking, no noise at all from outside or inside the hotel means a very sound sleep. Breakfast was ok (selection of meats, cheeses and eggs etc)
The food we had from the restaurant for the New Years meal was exception value and was well presented.
The rooms were only renovated 2-3 years ago but still feel a bit dated and have a very 90's ring to the decor. Rooms clean and tidy though so nothing too off putting ( most swiss hotels seem to go for the retro 90's look :/ pink bathroom tiles???)
Would class the hotel as a 3.5* rather than a 4* as the facilities and finish could be a bit smarter. (Compared to say the Hotel Beveldere across town which has some really swagger and character). Price is also very high for an midrange hotel (you are really paying for the views and location rather than for the hotel quality)
Overall, very happy with this hotel, staff very friendly and warm.
